Clinical and molecular diagnosis of a Costa Rican family with autosomal recessive myotonia congenital (Becker disease) carrying a new mutation in the CLCN1 gene
(Revista de Biología Tropical 56(1) p.1-11, 2006-08-18)
Myotonia congenita is a muscular disease characterized by myotonia, hypertrophy, and stiffness. It is inherited as either autosomal dominant or recessive known as Thomsen and Becker diseases, respectively. Here we confirm ...
Parental age effects, but no evidence for an intrauterine effect in the transmission of myotonic dystrophy type 1
(European Journal of Human Genetics p.1-8, 2014-07-23)
Myotonic dystrophy type 1 (DM1) is caused by the expansion of an unstable CTG repeat (g.17294_17296(45_1000)) with more repeats associated with increased disease severity and reduced age at onset. Expanded disease-associated ...
Identification and Functional Characterization of CLCN1 Mutations Found in Nondystrophic Myotonia Patients
Mutations in the gene coding for the skeletal muscle Cl− channel (CLCN1) lead to dominant or recessive myotonia. Here, we identified and characterized CLCN1 mutations in Costa Rican patients, who had been clinically diagnosed ...
A polymorphism in the MSH3 mismatch repair gene is associated with the levels of somatic instability of the expanded CTG repeat in the blood DNA of myotonic dystrophy type 1 patients
Somatic mosaicism of the expanded CTG repeat in myotonic dystrophy type 1 is age-dependent, tissuespecific and expansion-biased, contributing toward the tissue-specificity and progressive nature of the symptoms. Previously, ...
